"Evaluation Of Meat Spoilage Using A Chemiluminescence Flow Injection Analysis System Based On Immobilized Putrescine Oxidase And A Photodiode"
Lebensm. Wiss. Technol. 1996 Volume 29, Issue 5-6 Pages 498-502

Abstract: A convenient and highly sensitive analytical system was constructed for the estimation of microbial spoilage in meat. Putrescine and cadaverine produced by bacteria were degraded by an immobilized putrescine oxidase column and the hydrogen peroxide generated was determined by luminol chemiluminescence. Peroxidase from Arythromyces ramosus was used as a catalyst to obtain high sensitivity and a photodiode was used as the detector to construct a conventional chemiluminescence-flow injection analysis system. The calibration curves were linear in the 100 pmol/mL-200 nmol/L range for putrescine and 200 pmol/mL-80 nmol/mL for cadaverine. The coefficients of variation were 2.87%-3.15% for putrescine solution and 3.34% for the specimen solution. This system was able to detect putrescine and cadaverine after the bacterial count reached 4.3 P 10(6) cells/g in meat and the response increased with the increase in bacterial count. The regression equation between putrescine and cadaverine levels as determined by HPLC and this system was y=1.015x-0.501, and the correlation coefficient was 0.911.
